Background:

  • RNA secondary structures exhibit complex energy landscapes.
  • The Boltzmann-weighted ensemble often contains distinct clusters.
  • Minimum free energy structures may fall outside the main cluster.

Purpose of the Study:

  • To develop and provide methods for characterizing and visualizing the Boltzmann-weighted ensemble of RNA secondary structures.
  • To enhance the Sfold Web server with new features for ensemble analysis.

Main Methods:

  • Development of procedures to characterize and visualize the Boltzmann-weighted ensemble.
  • Implementation of clustering statistics, ensemble and cluster centroids, and multi-dimensional scaling.
  • Representation of the energy landscape for the Boltzmann-weighted ensemble.
